Product Overview and
Principle of Operation
MagnaValve® Description
The MagnaValve® WM 3000-24 is a normally closed valve that regulates the flow
of steel shot or grit in wheel-blast machines for blast cleaning applications. It is a
powerful valve with a flow rate capacity of up to 3,000 lb/min (1,361 kg/min) for
wheels up to 125 hp. The Remote Valve Driver for the MagnaValve comes with a 6-ft
cable for installation in the customer’s electrical panel, making it an ideal valve for
blast machines in high-temperature environments.
The MagnaValve reduces media usage, energy costs, machine downtime, and wear
and tear on equipment.
How It Works
The MagnaValve’s maintenance-free construction includes a rare earth permanent
magnet for normally closed operation and an electromagnet for controlling shot flow
rates. With power applied, the magnetic field is neutralized and shot is allowed to
flow through the valve. When no power is applied to the MagnaValve, the permanent
magnet stops all flow. If the power is interrupted for any reason, the permanent
magnet securely holds the shot.
The MagnaValve is factory tested and results are supplied upon request.
MagnaValve Controllers for Closed-Loop Operation
For an “automatic” closed-loop operation, an Electronics Inc. AC-24 Controller will
detect the current load on the wheel motor and regulate the flow of media to the
WM 3000-24. The WM 3000-24 MagnaValve, with the AC-24 Controller, provides
reliable, repetitive, and consistent media flow rates for blast cleaning applications.
The MagnaValve system makes it easy to document flow rates and establish or repeat
a good set-up.
